TWICE Members: Complete Guide to All 9 Members, Their Roles, and What Makes Each One Unique

With over 12 million albums sold, sold-out world tours across five continents, and a fandom that spans every corner of the globe, TWICE isn’t just a K-pop group — they are a full-blown cultural movement. Since their debut in October 2015, the TWICE members have redefined what it means to be a modern girl group: diverse, dynamic, deeply talented, and endlessly relatable.

Whether you’re a devoted ONCE who has followed every comeback since “Like OOH-AHH,” or someone who just discovered TWICE through a viral clip and wants to know more, this guide is for you. Here, you’ll find everything you need — complete profiles of all nine members, their official positions, unique personalities, solo milestones, and what makes each of them irreplaceable to the group’s identity.

This isn’t just a list of names. This is the definitive guide to understanding the women behind one of the most successful K-pop acts of all time.

Let’s meet them.

Who Are the TWICE Members? The K-Pop Group That Took Over the World

TWICE is a nine-member South Korean girl group formed by JYP Entertainment, one of the “Big Four” K-pop labels. The group was assembled through the brutal elimination reality show Sixteen in 2015, where trainees competed for a spot in the final lineup. Out of the original contestants, nine were chosen — and the rest, as fans say, is history.

What set TWICE apart from the very beginning was not just their synchronized performances or their bright, addictive pop sound. It was their multicultural identity. Five members are South Korean, three are Japanese, and one is Taiwanese — making TWICE one of the first major K-pop girl groups to achieve massive pan-Asian success while maintaining a strong global footprint.

Their fandom, officially called ONCE, is one of the most passionate and loyal communities in all of K-pop. The name reflects a beautiful promise from the group: “We will make you fall in love with us at once.”

They delivered on that promise — ten years and counting.

TWICE Members — In-Depth Profiles of All 9 Members

1. Nayeon (Im Na-yeon) — The Bright-Eyed Powerhouse

Born: September 22, 1995

Birthplace: Seoul, South Korea

Nayeon is the eldest member of TWICE and, in many ways, the face that launched a thousand fan edits. With her iconic bunny-like smile, sharp stage presence, and magnetic energy, she has been a consistent center figure since the group’s debut.

Before TWICE, Nayeon had already been training at JYP Entertainment for several years, coming remarkably close to debuting in an earlier project that was ultimately canceled. That perseverance defined her — when Sixteen began, she was already a polished performer, and it showed.

As a lead vocalist, Nayeon’s voice is bright and airy with a distinctly sweet tone that became central to TWICE’s early sound. Songs like “Cheer Up” and “Signal” feature her voice prominently in the opening lines — a placement that reflects her importance to the group’s identity.

In 2022, Nayeon made history as the first TWICE member to release a solo extended play, titled IM NAYEON. The lead single “POP!” debuted at No. 1 on the Gaon Digital Chart and charted internationally, proving she could command the spotlight entirely on her own.

What makes her unique: Nayeon is the rare kind of performer who looks equally at home in a high-energy dance break and a soft ballad. Her personality — outgoing, funny, occasionally dramatic in the most endearing way — translates perfectly through the camera. ONCE often describe her as the member who is impossible to ignore, even in a room full of stars.

2. Jeongyeon (Yoo Jeong-yeon) — The Cool, Steady Backbone

Born: November 1, 1996

Birthplace: Suwon, South Korea

If Nayeon is TWICE’s spark, Jeongyeon is their steady flame. The second oldest member, Jeongyeon is widely recognized for her distinctly deep and rich vocal tone — a quality that stands out beautifully in a group known for brighter, higher voices.

Jeongyeon became a cultural icon within K-pop for embracing short hair at a time when long hair was almost universally expected of female idols. Her androgynous, cool style resonated with a huge number of fans who appreciated her refusal to conform to conventional beauty standards.

She is also known within TWICE for her older-sister energy — direct, caring, and fiercely protective of her members. In interviews and reality content, Jeongyeon is often the one who says exactly what she’s thinking, which fans find refreshing and deeply authentic.

In recent years, Jeongyeon faced significant health challenges, including issues with her spine and anxiety-related conditions that required her to step back from certain activities. Her openness about those struggles, and her determined return to the stage, made her one of the most emotionally resonant figures in the group for ONCE worldwide.

What makes her unique: Jeongyeon proves that a strong identity doesn’t require conformity. Her vocal color, her personal style, and her emotional honesty make her one of the most three-dimensional members in the group — someone whose presence you feel even in the spaces between the notes.

3. Momo (Hirai Momo) — The Dance Machine

Born: November 9, 1996

Birthplace: Kyōtanabe, Osaka, Japan

There is a story TWICE fans never forget: during the filming of Sixteen, Momo was eliminated from the competition. JYP Entertainment’s founder, Park Jin-young, made the difficult call — and then reversed it, bringing her back because her dancing was simply too extraordinary to leave out.

That decision changed K-pop history.

Momo is TWICE’s main dancer, and by many industry measures, one of the finest dancers in K-pop today. Her movement quality is exceptional — powerful yet precise, emotional yet technically flawless. Whether she’s performing a sharp hip-hop routine or a fluid contemporary piece, Momo commands the stage in a way that is genuinely rare.

Born in Osaka, Japan, Momo trained at JYP after being scouted through an open audition in Japan. She has spoken candidly about the difficulties of moving to South Korea as a teenager, learning a new language, and adapting to a new culture — all while training intensely to become a professional performer.

Off stage, Momo is beloved for being the group’s most enthusiastic food lover — a recurring and genuinely charming theme across TWICE’s reality shows and variety content. Her warm, goofy, relatable personality has earned her devoted fans who love her as much for her humor as for her jaw-dropping performances.

What makes her unique: Momo represents something powerful: that pure, relentless dedication to craft can take you from nearly cut to globally celebrated. She is living proof that talent, when matched with discipline, becomes something undeniable.

4. Sana (Minatozaki Sana) — The Charming Scene-Stealer

Born: December 29, 1996

Birthplace: Tennōji, Osaka, Japan

Ask any K-pop fan about Sana, and watch their face light up. There is something almost impossible to define about Sana’s appeal — a magnetic warmth, a gift for making any moment feel joyful, and an ability to go viral without even trying.

She is perhaps best known internationally for the “Shashasha” moment from TWICE’s reality show — a spontaneous, playful ad-lib that became one of the most replicated K-pop memes of the last decade. That single clip introduced millions of people to TWICE and, more specifically, to Sana’s irresistible energy.

As a vocalist, Sana has a soft, gentle timbre that suits TWICE’s more tender, romantic tracks beautifully. But it is her presence — on stage, in interviews, in fan interactions — that truly defines her role in the group. She is the member who fills every room with warmth.

Originally from Osaka, Sana was recruited by a JYP talent scout on the streets of Japan and made the bold decision to move to Korea and pursue her dream. Her journey from a regular teenager in Japan to one of K-pop’s most beloved figures is the kind of story that makes the genre endlessly compelling.

What makes her unique: Sana possesses an emotional expressiveness that is both genuine and captivating. She does not perform charm — she simply is charming. In a world of carefully managed idol images, that authenticity is extraordinarily valuable.

5. Jihyo (Park Ji-hyo) — The Heart and Soul of TWICE

Born: February 1, 1997

Birthplace: Goyangsi, Gyeonggi-do, South Korea

To understand Jihyo is to understand TWICE. She is the group’s official leader and main vocalist, and she carries both roles with a quiet, immovable strength that has been the backbone of the group’s decade-long journey.

Jihyo’s backstory is one of the most remarkable in all of K-pop. She began training at JYP Entertainment at the age of eight — and trained for a full ten years before debuting with TWICE in 2015. Ten years of sacrifice, uncertainty, and dedication before the world finally got to hear her voice.

And what a voice it is. Jihyo’s vocals are powerful, resonant, and emotionally complex — capable of both explosive high notes and deeply tender, nuanced delivery. Her live performances are consistently cited as among the strongest in K-pop, and she brings a raw emotional authenticity to every song she performs.

As leader, Jihyo is responsible for the group’s cohesion — on stage and off. In behind-the-scenes content, she is the one who gives speeches before performances, who checks on members who are struggling, and who speaks on behalf of the group in difficult moments. Her leadership style is not loud or authoritarian — it is deeply empathetic and deeply effective.

In 2023, she released her solo debut album ZONE, which was met with widespread critical acclaim and demonstrated a more mature, vulnerable artistic dimension that many fans had long wanted to see explored.

What makes her unique: Jihyo is, in every sense, the center of gravity for TWICE. She holds the group together not through authority, but through love — and that quality, more than any vocal run or performance, is what makes her irreplaceable.

6. Mina (Myoung Eui-jin) — The Elegant Black Swan

Born: March 24, 1997

Birthplace: San Antonio, Texas, USA (raised in Kobe, Japan)

If TWICE were a ballet company, Mina would be the prima ballerina. Graceful, precise, and possessing a quiet elegance that is entirely her own, Mina brings a dimension to TWICE that no other member replicates — a classical refinement that elevates every performance she is part of.

Mina’s origin story is genuinely cinematic. She was discovered by a JYP Entertainment talent scout while attending a ballet performance in Japan — not as a performer, but as an audience member. The scout recognized something extraordinary in her and invited her to audition. She had no prior idol training, no experience with the K-pop industry, and no particular plan to become a pop star. She simply had an innate grace and presence that could not be taught.

She passed the audition and, after years of rigorous training, debuted with TWICE in 2015 as a lead dancer and vocalist. Her ballet background is visible in everything she does — the line of her arms, the control of her movements, the way she occupies space on stage with deliberate, considered intention. Fellow choreographers and dancers within the K-pop industry have consistently praised her technical precision.

Off stage, Mina is known for her quiet, introverted nature. She is thoughtful, artistic, and deeply private — a contrast to some of her more outwardly expressive members, but a contrast that makes the group’s dynamic richer. In TWICE’s variety content, Mina’s dry humor and occasional unexpected wit have become a beloved source of surprise for fans who expect nothing but serenity.

In 2019, Mina publicly stepped back from group activities due to anxiety and panic disorder — a disclosure that was both courageous and profoundly important for mental health conversations within K-pop culture. At the time, the industry rarely acknowledged idol mental health openly. Mina’s honesty, and JYP Entertainment’s decision to support her recovery rather than push her back into the spotlight, set a meaningful precedent. Her return to the stage — visibly stronger, more settled, and more expressive than ever — moved fans deeply and reminded the world that rest and recovery are not weaknesses.

What makes her unique: Mina is TWICE’s quiet masterpiece. She does not need to be the loudest presence in the room to be the most memorable one. Her artistry is deliberate, her elegance is effortless, and her journey from reluctant recruit to beloved global idol is one of the most compelling stories the group has to offer.

7. Dahyun (Kim Da-hyun) — The Sunshine Entertainer

Born: May 28, 1998

Birthplace: Seongnam, Gyeonggi-do, South Korea

Long before Dahyun was a TWICE member, she was already going viral. A fancam of her performing a traditional Korean fan dance at a school talent show — specifically, a moment where she locked eyes with the camera with the intensity of someone who had been performing for decades — spread rapidly online and eventually reached the eyes of JYP Entertainment’s scouting team. She was invited to audition, and the rest is exactly the kind of story K-pop was made for.

Dahyun is TWICE’s lead rapper and vocalist, but those titles barely capture what she actually contributes to the group. She is, in the most generous and accurate sense of the phrase, a natural entertainer. Her comedic timing is impeccable. Her variety show instincts are sharp enough to make professional TV hosts look slow. And her ability to connect with audiences — through humor, through honesty, through sheer radiant energy — is a gift that cannot be manufactured.

Fans will forever associate Dahyun with the “Eagle Dance,” a spontaneous, arms-wide, completely unself-conscious move she broke out during a fan event that became one of TWICE’s most iconic and beloved memes. It perfectly encapsulates what she brings to the group: pure, unfiltered joy.

But Dahyun is more than a comedian. She is also one of the group’s most emotionally intelligent members — perceptive, caring, and deeply connected to ONCE in a way that feels personal rather than performative. In fan meetings and letter readings, she is frequently the member who speaks with the most directness and emotional honesty, and fans respond to that authenticity with fierce loyalty.

Her rapping style is bright and rhythmic, suited perfectly to TWICE’s upbeat, feel-good discography. And as the group has matured into more sophisticated sonic territory, Dahyun has grown alongside them — showing versatility and depth that earlier in her career she was not always given the space to demonstrate.

What makes her unique: Dahyun is the member who reminds you that joy is a serious skill. Making people feel genuinely happy — not just entertained, but happy — is harder than it looks, and Dahyun does it with a consistency and sincerity that is one of TWICE’s most underrated superpowers.

8. Chaeyoung (Son Chae-young) — The Artistic Maverick

Born: April 23, 1999

Birthplace: Seoul, South Korea

In a group celebrated for its bright, cohesive aesthetic, Chaeyoung has always been the one quietly coloring outside the lines — and making it look like the most natural thing in the world.

She is TWICE’s main rapper and vocalist, and her artistic identity is the most distinctly individual of any member in the group. Chaeyoung is a trained visual artist, a writer, a fashion risk-taker, and a musician with a clear creative vision of her own. Long before tattoos became more accepted in Korean idol culture, Chaeyoung was wearing hers openly — a quiet but deliberate statement of artistic selfhood that resonated with a generation of fans who value authenticity over conformity.

Her rapping style reflects her personality — controlled, confident, and lyrically thoughtful. Unlike the more playful, rhythmic approach of Dahyun, Chaeyoung’s rap delivery carries a cool, self-possessed edge that suits TWICE’s more mature, edgier material particularly well. As the group’s sound evolved from bubblegum pop into more complex sonic territory with albums like Formula of Love and READY TO BE, Chaeyoung’s contributions became increasingly central.

She is also a songwriter, having contributed to the writing of several TWICE tracks — a fact that places her in a smaller, more creatively independent tier within the group. For fans who are interested in the members as developing solo artists, Chaeyoung is arguably the one whose individual artistic trajectory is most worth watching.

Off stage, she is known for her deep love of art, her distinctive personal style, and a quietly confident personality that does not seek the spotlight but commands it naturally when it arrives.

What makes her unique: Chaeyoung represents creative integrity within a system that can sometimes discourage it. She is building an artistic identity that will outlast any single era or comeback — and in doing so, she is expanding what it means to be a TWICE member.

9. Tzuyu (Chou Tzu-yu) — The Maknae with a Commanding Presence

Born: June 14, 1999

Birthplace: Tainan, Taiwan

Tzuyu is TWICE’s maknae — the youngest member — and yet there is nothing about her presence that reads as small, uncertain, or inexperienced. From the moment she appeared on Sixteen as a fifteen-year-old with striking visuals and a composure far beyond her years, it was clear that Tzuyu was something extraordinary.

Discovered by a JYP talent scout at a performing arts exhibition in Taiwan, Tzuyu relocated to South Korea as a young teenager to train — far from her family, in a country with a different language and culture, under enormous pressure to perform. The fact that she did so with the grace and steadiness she has consistently displayed speaks to a remarkable inner strength.

As TWICE’s lead dancer and vocalist, Tzuyu’s performance style is commanding and precise. She has a natural physical presence on stage — tall, poised, and expressive in a way that photographs and records beautifully. She is frequently cited as one of K-pop’s most visually striking performers, and while that designation can sometimes reduce an artist to their appearance, Tzuyu has consistently demonstrated the work ethic and stage skill to back it up entirely.

Beyond the stage, Tzuyu is known for being quietly reserved — thoughtful and warm with those she trusts, but measured in public settings. Her deep love for her home country of Taiwan has been a consistent and meaningful part of her public identity, and she remains one of the most prominent and beloved Taiwanese figures in the global K-pop landscape.

She is also known within the ONCE community for her archery hobby — a pursuit she has spoken about with genuine enthusiasm, and one that feels perfectly suited to her: focused, disciplined, requiring absolute precision.

What makes her unique: Tzuyu carries the weight of being the group’s youngest member and its most visually prominent figure — two pressures that could easily overwhelm — with a maturity and quiet dignity that has earned her deep respect both inside and outside the fandom. She does not just represent TWICE. In many ways, she represents the graceful face of a new generation of K-pop.

What Makes TWICE’s Group Dynamic So Special?

Understanding the individual TWICE members is important. But understanding how they work together is what reveals the true secret of the group’s enduring success.

A Multicultural Lineup That Broke K-Pop Norms

When TWICE debuted in 2015 with five Korean members, three Japanese members, and one Taiwanese member, it was a deliberate and strategic decision by JYP Entertainment — but it became something far more significant than a business strategy. It became the group’s identity.

The multicultural lineup allowed TWICE to speak to audiences across East Asia in a way that few K-pop groups had managed before. In Japan, they became one of the best-selling foreign acts in the history of the Oricon charts. In Taiwan and across Southeast Asia, they built a devoted following that continues to grow. And internationally, their diversity signaled an openness and inclusivity that resonated with global audiences increasingly hungry for representation.

For Momo, Sana, and Mina, performing in a language that was not their first — navigating a culture that was not their native one — required extraordinary dedication. Their success in doing so has made them role models not just for aspiring idols, but for anyone who has ever had to build a life far from home.

The “One for Everyone” Phenomenon

One of the most frequently discussed aspects of TWICE’s appeal is what fans call the “one for everyone” quality of the group’s membership. With nine members representing such a wide range of personalities — from Nayeon’s extroverted brightness to Mina’s quiet elegance, from Dahyun’s joyful humor to Chaeyoung’s artistic independence — virtually every fan finds a member they connect with on a personal level.

This is not accidental. The diversity of personality within TWICE creates a group that functions like a prism: a single light source that refracts into nine distinct, beautiful colors. Each member attracts fans through their own unique appeal, and those fans then become invested in the group as a whole.

The result is a fandom that is unusually broad — spanning demographics, nationalities, and musical preferences — and unusually loyal. ONCE do not just love TWICE. They love their TWICE member, and through that love, they love the group.

Individual Identities That Strengthen the Whole

Perhaps the greatest achievement of TWICE as a group is that they have managed to maintain a strong, cohesive group identity while simultaneously allowing — and encouraging — each member to develop as an individual artist. This balance is genuinely difficult to achieve in the K-pop system, where group uniformity is often prioritized above all else.

As TWICE has matured, JYP Entertainment has given members increasing freedom to express their individual artistry — through solo albums, self-composed tracks, individual fashion choices, and personal creative projects. Rather than fragmenting the group, this approach has deepened ONCE’s investment in both the individuals and the collective.

TWICE Members’ Solo Careers — Growing Beyond the Group

The solo careers of TWICE members represent one of the most exciting dimensions of the group’s current chapter. Each solo project has revealed a new facet of the member involved — and collectively, they paint a picture of a group that is far more musically diverse than any single TWICE comeback could fully express.

Nayeon led the way with IM NAYEON (2022) and NA (2023), establishing herself as a solo pop force with a bright, confident sound that felt both distinctly her own and entirely consistent with what fans love about her.

Jihyo delivered ZONE (2023), a sophisticated R&B-influenced project that showcased a deeper, more vulnerable artistic identity — and received some of the strongest critical reviews of any TWICE solo release to date.

Chaeyoung has been building toward a solo debut with creative projects and songwriting contributions that suggest her individual release, when it comes, will be among the group’s most artistically adventurous.

Momo, Sana, and Mina have participated in Japanese unit activities and individual Japanese releases that have expanded TWICE’s presence in one of K-pop’s most valuable markets.

The solo careers of TWICE members do not compete with the group — they complement it, offering fans additional dimensions of the artists they already love while demonstrating that TWICE’s collective strength is built from nine genuinely individual talents.
